[Asterisk-Users] Good FXO for UK use.

[Razza]

Got a feeling that the same card I bought from goods2world.co.uk, which
gave me terrible echo problems, due to the impedance mismatch of the US
telco network (600ohm) versus the BT network.
 
When using that card all seemed to disconnect fine, I assume the issue
lies with the TDM400/FXO daughter board.

I just bought a DigitNetworks card called "DigitNetworks X100P - FXO PCI
card" which supposedly is compatible with the discontinued Digium X100P
card. This is a single port FXO card. Tell me how to test for the TDM400
problem and I'll perform a test and post my results back to the list.
The card is dead cheap $25 (but $36 :-( for shipping ).
 
Regards Johan.

This maybe an out of place comment but it would appear Digium show
little to no interest in non-North American implementations, do we know
if they are ever going to resolve this issue? or indeed how much it
would cost? Based on my experience I'm sure there are a number of UK
based people who could jointly fund such a development for a reasonable
FXO product?

No the TDM400 does not work, it does not detect calling party
termination correctly, so IVR and voicemail do not see the caller hang
up on BT lines. Digium are aware of the problem, but fixing it doesn't
seem to be a high priority, despite the fact that they have been
supplied with detailed technical information regarding BT line behaviour
:-(.

Patrick is right about this , I get 20 or so seconds of solid tone at
the end of all my voicemails,
but I can live with this for the sake of no echo.
